A California UPS worker who police say threatened a mass shooting was arrested Sunday, and police found more than 20,000 rounds of ammunition and several weapons including tactical-style rifles in his home.

Thomas Andrews, 32, sent threatening messages to his employer, the Sunnyvale Department of Public Safety said in a statement posted on Facebook. The text messages said Andrews was planning a mass shooting at the UPS in Sunnyvale, the department said.

Police launched an investigation and learned Andrews was the registered owner of four handguns and a rifle, Sunnyvale DPS said. Patrol officers found Andrews and attempted to pull him over late Sunday night, but he led officers on a car chase.

He was eventually captured with help from the California Highway Patrol, according to the department.

After Andrews was apprehended, police searched his home and found more than 20,000 rounds of handgun and rifle ammunition, numerous high capacity magazines, five tactical-style rifles, a shotgun, three handguns and body armor, according to officials.

Tactical backpacks with ammunition were staged at the front door, the department said.

A UPS spokesman told USA TODAY that the company is aware of the situation and cooperating with authorities but had no further comment.

Andrews was arrested and booked into the Santa Clara County Jail on charges of making criminal threats, evading police, driving under the influence and "several counts of weapons violations," according to Sunnyvale police.
